Red Wedding KEEP ROB ALIVE

[okyman]

So i was going to attempt to keep Rob alive during the red wedding.  I saved when i got the letter.  I was enlisted in Robs army for both of these attempts.  First, i was actually with Rob in his army and got the note that he died.  Then i was instantly taken prisoner even though i was in winterfell with rob...  So i reloaded and this time took leave from Rob, and went to wait at the twins.  I still got the note.  But back in Winterfell Rob is still alive and well.  I didnt have any battle or anything.  But the note still reads that he was killed and i guess the game with progress as such?

EDIT:  When i returned to Robb he said "Prepare to die scum" and we have a relation of 33...  He was in the lords hall of Winterfell so there was no reply options and no battle...  Also he is removed from the character list so i think i will let him die...  seems buggy lol
